Slide to frame metalurgy on the P series Rugers?

[His lordship.]

I have read of the problems with galling when you have stainless steel slides and stainless steel frames, one was even a kimber Model 1911 that had this happen after putting 5,000 rounds through it and using the proper lube.

I am thinking of getting one of the P series Ruger pistols in 9 MM, either the aluminum frame or the polymer frame and was wondering what type of steel is used on the frames?  At least I know that the slide is stainless steel.  I have a Ruger GP 100 in blued steel that has stainless trigger and hammer parts, so I am concerned that at least with the polymer framed gun, the slide rails might be stainless.  Anyone with this type of pistol, does it seem to be stainless or carbon steel as far as the frame rails are concerned?

Thanks.

I have one of the first polymer frame P-95 9 mm that came out. Bought it within the first year they came out. Frame rails on mine are the same as the polymer frame or are at least covered in polymer if they are some type metal. I also have an alloy frame, steel slide P-94 in 40 cal. Both guns will feed and eject any ammo I have ever tried and I have never had a malfunction of any kind with either. Only factory ammo has been used in both, no reloads. Highly recommend either of them if you want a solid, dependable pistol. They are not target pistols, but they run.
